.SH "DESCRIPTION"
The current MadWifi driver supports multiple APs and concurrent AP/Station
mode operation on the same device.  The devices are restricted to using the
same underlying hardware, thus are limited to coexisting on the same channel
and using the same physical layer features. Each instance of an AP or station
is called a Virtual AP (or VAP). Each VAP can be in either AP mode, Station
Mode, "special" station mode, and Monitor mode. Every VAP has an associated
underlying base device which is created when the driver is loaded.

.SH "ARGUMENTS"
.TP
.B <vap> create [nounit] wlandev <base device> wlanmode <mode> [uniquebssid]
Create the interface <vap> using the specified <base device> and <mode>. <vap> can either be a full interface name (e.g. 'ath0'), or just the suffix (e.g. 'ath'), in which case, the kernel will automatically append the next vacant integer. [nounit] will turn off the automatic integer increments.
.TP
.B <vap> destroy
Removes the given VAP interface. You must specify the full interface name. I.e 'ath0' rather than just 'ath'.
.TP
.B <vap> list <list item>
Show information about connected peers, keys, channels etc.
.PP
.SH "AVAILABLE MODES"
.TP
.B ahdemo
Create the station in ad-hoc demo (aka pseudo IBSS) mode.
.TP
.B adhoc
Create the station in ad-hoc mode.
.TP
.B ap
Create the VAP in AP mode.
.TP
.B monitor
Create the station in monitor mode.
.TP
.B sta
Create the VAP in station mode.
.TP
.B wds
Create the station in WDS mode.
.PP
.SH "OPTIONS"
.TP
.B uniquebssid
Create the VAP using a new unique MAC address, different from the underlying device.
.TP
.B bssid
Synonym for uniquebssid, for backward compatibility.
.TP
.B \-bssid
Ignored for backward compatibility.
.TP
.B nosbeacon
Ignored for backward compatibility.
.PP
.SH "LIST ITEMS"
.TP
.B sta or no parameters.
Show information on associated stations.
.TP
.B scan or ap
List all visible stations.
.TP
.B chan or freq
List all channels and frequencies.
.TP
.B active
List all available channels and frequencies.
.TP
.B keys
List all of the keys associated with the VAP
.TP
.B caps
List the capabilities of the given VAP.
.TP

List WME (Wireless multimedia extensions, aka WMM) parameters.
.PP
.SH "EXAMPLES"
.TP
\fBwlanconfig ath create wlandev wifi0 wlanmode sta
Create a station mode VAP, using wifi0 as the underlying device. The interface wil be called athN, where N is the first free integer. The MAC address will be the same as the underlying device.
.TP
\fBwlanconfig ath0 create wlandev wifi0 wlanmode sta
Create a station mode VAP (ath0) using wifi0 as the underlying device. The MAC address will be the same as the underlying device.
